Hello! I was also looking into lowering options for the G310R since I am a short guy with short legs and short inseam... Before I bought the G310R, I was lucky enough to check out the lowering seat fitted on my bike before I rolled away with it, and I have to say, the difference is minimal. For the few minutes I sat on it, here is my opinion:
- the seat felt more comfortable in the sense that it was narrower than stock.
- the thickness of the cushion was noticeably gone and gave it a harder feel under my butt.
- for the price that BMW is asking for this lowered seat, it didn't feel worth the money to me.
I am able to get my toes down not all the way to the balls of my feet (for both feet), and I can get a single flat foot down at a light IF i tip the bike at a slight angle or slide over a bit. This is OK for short rides (commutes) but if you have to do this all day long for extended periods, I can see how it can be a pain ... I'm not chiropractor or anythng, but I feel like the weight of the bike and the shifting over with your hips can contribute to some bad hip alignments later on... MAYBE???
In any case, I went ahead with stock everything, and already dropped the bike once in a parking lot with SUPER uneven surface. From when the bike started to tip over to the right, and when my right foot found flat ground, the bike was tipped too far over to stop it. *sigh* That was a moment where i thought to myself "man... if I was able to flat foot on both sides..."
I'll probably get used to how things are ... but I hope whichever way you choose, it works out for you and you don't drop your bike because of something stupid like what I did!
There was a post I saw by
who found some company that made what looks to be a legit lowering suspension kit (which is what I think I would do IF I still want to lower) ... seems costly, but in my opinion, it feels like it's doing it "right".
I don't know if this will fit on the GS, but might be a good starting point if you wanted to take this path.
